As a standard, all our square, non-tapered PVC wraps come complete with a Box (Craftsman) cap and base. If the Georgian style better suits your project, we can substitute this Capitol Set (to be installed on site). Both parts are made from PVC mouldings to last a lifetime. The upgrade price covers columns from 6” to 12" square and adds 4 3/4" to the size of the shaft.  Alternatively, the standard box cap adds 1 1/2" to the size of the shaft.
